SCRAPER.

SPECIFICATION forming part of Letters Patent No. 435,712,

dated September 2,1890.

Application filed November 25, 1889- Serial No. 331,467. (No model.)

To all whom, it may concern.-

Be it known that I, \VILLIAM E. PUGSLEY, of Parker, in the county ofTurner, and in the State of South Dakota, have invented certain new anduseful Improvements in Scrapers; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to scrapers; and it consists in certainpeculiarities of construction and combination of parts to be hereinafterdescribed, with reference to the accompanying drawings, and subsequentlyclaimed.

In the drawings, Figure 1 represents an elevation of a scraperconstructed according to my invention, certain of the parts beingbrokenaway for the purpose of better illustration; Fig. 2, a plan view of themachine, and Figs. 3 and a vertical transverse sections with partsbroken away, these latter views serving to clearly illustrate the meansfor adjusting the scraping-blade.

Referring by letter to the drawings, A rep resents a curved yokeprovided with brackets B, that support a laterally-adjustable rear axleC of the machine, this axle being held in its adjusted position byset-screws l) or other suitable means, and, as best shown in Fig. 4, theends of this axle are cranked to receive the hubs of the rear wheels Dof the machine.

Extended forward from the yoke A are curved parallel arms E, united attheir forward ends by a plate 0, that rests upon a fifth- Wheel d on anaxle F for the front wheels G of the machine, said axle being providedwith a stud e, that extends up through a perforation in the plate thatunites said arms, as is best illustrated in Fig. 1.

Supported on the curved arms E near the front of the machine is adrivers seat II and foot-rest I, and slipped onto the stud c on the axleE is the perforated forward end f of a truss J, this end of the trussbeing held against vertical displacement by a washer g and pin it orother suitable means, and the rear end of said truss is connected bychains h to the yoke A, whereby this latter end of the truss is free torise or lower, but is prevented from switching from side to side. Therear portion of truss J is provided with a guide 2' for a horizontalskeleton frame K, that is pivoted to said truss and has a segmental rearportion j, provided with a series of perforations k for engagement witha pin m, that passes through the truss to hold the skeleton frame in anyposition to which itmay be pivotally adj usted. The skeleton frame K isprovided with a series of depending arms at, and to these arms issecured the scraping-blade L of the machine, the angle of the latter tothe line of draft being regulated by the pivotal adj ustment of theskeleton frame, this adjustment being effected by means of a chain orcord 0, attached to an end of said frame, run over a pulley p on thetruss J, and connected to a vertical winch M, that has its bearings onthe rear portion of said truss. The scrap ing-blade L is preferably ofchilled steel and concave upon its working-face.

Near its rear end the truss J is provided with lateral upturned ears (1for the reception of a transverse rod N, and secured to the ends of thisrod are standards 0, that extend upward through guides r on the yoke A,these guides being provided with bearings for pulleys s t,'over whichare run chains or cords to r, connected to the upper and lower ends ofsaid standards and to vertical winches P, the

latter having their bearings on the brackets B, as is best illustratedin Figs.1 and 4:. The cords to are arranged to wind on the winches Pin adirection opposite to the wind of the cords o, and in consequence ofthis arrangement the scraping-blade Ii has a positive verticaladjustment in either direction, it being obvious that when one set ofcords are winding the other set are unwinding in the same proportion.The ends of the yokeA are con nected by a transverse rod Q, andpivotally connected to this red is a platform R, supported in positionfor use by means of chains S, attached to the brackets B, said platformbeing for the use of the man or men'who attend to the adjustment of thescraping-blade.

As shown in Fig. 2, the front axleF is provided with hounds T for theattachment of a tongue or other suitable draft mechanism.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In ascraper, the combination ofthe truss J, provided with the rearguide i, the horizontal frame K, pivotally connected to the truss andprovided with the mental rear portion 7', the pin m, for engagement withthe guide and a perforation in said segmental portion of the frame, thescraping-blade L, connected to said frame, the pulley 10 and winch M onsaid truss, and the flexible device 0, passed around the pulley andconnected at its ends to said winch and pivoted frame, substantially asset forth.

2. In a scraper, the combination of the yoke A, provided with guides 7'and brackets B, a truss, a scraping-blade suspended from the truss,vertical standards 0, connected to said truss to engage said guides,winches P, journaled in said brackets, the pulleys s t, and the flexibledevices to 11, passed over said pulleys to connect with opposite ends ofthe stand ards and wind on the Winches in opposite directions,substantially as set forth.

perforated seg- 3. In a scraper, the combination of the yoke A, providedwith the guides r and brackets 13, the truss J ,having verticalstandards 0 connected thereto and engaged by said guides,

the stay-chains h, connecting the yoke and.
